The best way to transition is just to read how bad animal and animal products are for our health. You can google it or you can watch all those documentaries such as "Forks Over Knives" etc and they will explain it to you. You can also join vegan online communites such as www.30bananasaday.com and such for support. There is also a great vegan book called the "80-10-10 Diet" by Douglas Graham which shows why you should be a vegan.
